Summary: A novel nanocomposite (0.2TiO(2) + AC) with two promising applications is demonstrated, as an additive for promoting hydrogen storage in magnesium hydride and as an active electrode material for hosting lithium in Li ion batteries. Transmission electron microscopy study provides evidence that well dispersed TiO2 nanoparticles are enclosed by amorphous carbon nets. The nanocomposite is thermally stable up to similar to 400 degrees C according to a thermogravimetry-differential scanning calorimetry (TG-DSC) study. Volumetric hydrogen storage tests and DSC studies further prove that a 3 wt% of 0.2TiO(2) + AC nanocomposite as additive lowers the dehydrogenation temperature of MgH2 over 100 degrees C and maintains the performance consistency. As a working electrode for Li ion battery, 0.2TiO(2)+AC offers a reversible capacity of 400 mAh/g at the charge/discharge rate of 0.1C and consistent stability up to 43 cycles with the capacity retention of 160 mAh/g at 0.4C. These cost-effective high-performance materials with applications in two promising areas of energy storage are highly desired for progressing towards sustainable energy development.

Summary: 3D porous flower-like Ni/Zn-MOFs are synthesized via a solvothermal method, and the morphology evolution from plate to 3D flower is governed by a nucleation-dissolution-renucleation mechanism. The obtained nonstoichiometric bimetallic carbide-containing composites (Ni3ZnC0.7/ Ni/ZnO composites) show stable hydrogen absorption and dehydrogenation properties. The addition of Ni3ZnC0.7 and Ni catalysts in the composite improves the hydrogen storage capacity and reduces the activation energy.
